Strengthening cross-border law enforcement cooperation in the EU: the Prüm network of data exchange

The Prüm network was established to provide mechanisms and the infrastructure to achieve a closer cooperation between the EU member states in combating terrorism, organised crime and illegal immigration through the cross border exchange of DNA profiles, fingerprints and vehicle registration data. While Prüm offers clear benefits for cross-border policing, it continues to present challenges of a technical and scientific nature as well as legal, ethical and socioeconomic concerns. This article reviews these challenges as well as the existing safeguards. It argues that, in order to achieve Prüm benefits and maximise its potential, it is important to enhance the necessary dialogue and cooperation between member states so as to confront the above concerns and address challenges posed by Prüm through balanced measures.
